EarthQuaker Devices / Dr. Z ZEQD-Pre All-Analog Tube Preamp

Preamps have really grown to become one of my favorite pedal genres over the last couple years, and when two powerhouse companies form a partnership on a new preamp creation, that makes us all pretty excited. The ZEQD-Pre All-Analog Tube Preamp is a collaboration between EarthQuaker Devices and Dr. Z Amplification, bringing the best of both their worlds together for a new and game-changing design. With multiple routing options, an additional boost section and utilization of a real EF86 tube, this high-end machine will be welcomed on pedalboards and studios across the globe…

The ZEQD-Pre is an all-analog tube preamplifier brings together EarthQuaker Devices’ innovative pedal design and Dr. Z Amplification’s decades of tube amp expertise. With a passive three-band EQ, professional headphone output, balanced XLR output, and onboard analog cabinet simulation, the ZEQD-Pre delivers authentic tube warmth and dynamic response in a complete analog amplifier system that fits right on your pedalboard. The ZEQD-Pre uses the EF86 pentode—the same tube that gives many Dr. Z amplifiers their pristine hi-fi tone and makes them such responsive pedal platforms.

Run the balanced XLR output straight into any console or interface and use the ZEQD-Pre as your main amp. The analog cabinet simulation is there when you need it, or flip the Cab Bypass switch to send a pure signal to your preferred IR loader or modeling software. Perfect for direct recording, backline-free gigs, or hybrid rigs with multiple signal paths. The headphone output features built-in analog cabinet simulation for a realistic amp feel during quiet practice sessions. Enjoy the full EF86 tube character without disturbing your housemates.

All outputs work simultaneously, even when the pedal is bypassed. Send your signal to an amp, route a direct feed to front-of-house, and monitor through headphones—all at once. This routing flexibility makes the ZEQD-Pre an invaluable studio tool.

Touch Sensitivity: The EF86 responds to every dynamic nuance in your playing. Play lighter and it cleans up; dig in and it blooms. Natural expression that follows your hands.
Full-Frequency Clarity: Extended response means harmonic richness without sacrificing definition. Bass notes stay tight, highs remain bell-like and clear.
Responsive EQ: Higher voltage and broader bandwidth let the passive Three-Band EQ shape your tone effectively with minimal signal loss. The interactive controls behave like classic tube amp tone stacks—predictable and musical across their entire sweep.

In the demo I created, I explore the tonal differences between each of the differing output options, as well as seeing how the ZEQD-Pre sounds with some additional effects added on. It has a warm, analog sound, shaping your tone and punching in some grit when you need it, laying down a smooth, satisfying base sound with ease.
